killall pflogd
kill $(pidof pflogd) # ggf auch in einer while-schleife

danke auch für dein feedback.

Beispiel mit einem Schleiferl, weil man da noch viel andere sinnvolle Sachen machen kann (loggen, Screenoutput etc.):

for i in `ps -ef | grep _pflogd | awk '{print $2}'`; do kill $i; done

P.S.: falls du dir mit den Backticks schwertust, verwende einfach den $( ) Syntax

for i in $(ps -ef | grep t | awk '{print $2}'); do kill $i; done

ich machs immer so (ist länger als Deins):

kill -9 `ps -ef | grep -i processname | grep -v $$ | awk '{ split ($0, xout, " "); print xout[2]}'`

imo hast bei dem unteren Beispiel die falsche Apostrophsetzung.

` wäre imo richtig

kill `top | grep _pflogd | cut -c1-5`

also einfach `statt '

Keine Ahnung was du für ein seltsames System hast wo kill ohne killall installiert ist...jedenfalls wirst du es wohl doch irgendwo herbekommen oder?

KILLALL(1) User Commands KILLALL(1)
NAME
killall - kill processes by name
SYNOPSIS
killall [-Z,--context pattern] [-e,--exact] [-g,--process-group] [-i,--interactive] [-q,--quiet] [-r,--regexp] [-s,--signal signal]
[-u,--user user] [-v,--verbose] [-w,--wait] [-I,--ignore-case] [-V,--version] [--] name ...
killall -l
killall -V,--version
DESCRIPTION
killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g. -HUP) or by number (e.g. -1) or by option -s.
If the command name is not regular expression (option -r) and contains a slash (/), processes executing that particular file will be
selected for killing, independent of their name.
killall returns a zero return code if at least one process has been killed for each listed command, or no commands were listed and at
least one process matched the -u and -Z search criteria. killall returns non-zero otherwise.
A killall process never kills itself (but may kill other killall processes).
OPTIONS
-e, --exact
Require an exact match for very long names. If a command name is longer than 15 characters, the full name may be unavailable
(i.e. it is swapped out). In this case, killall will kill everything that matches within the first 15 characters. With -e, such
entries are skipped. killall prints a message for each skipped entry if -v is specified in addition to -e,
-I, --ignore-case
Do case insensitive process name match.
-g, --process-group
Kill the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes
belonging to the same process group were found.
-i, --interactive
Interactively ask for confirmation before killing.
-l, --list
List all known signal names.
-q, --quiet
Do not complain if no processes were killed.
-r, --regexp
Interpret process name pattern as an extended regular expression.
-s, --signal
Send this signal instead of SIGTERM.
-u, --user
Kill only processes the specified user owns. Command names are optional.
-v, --verbose
Report if the signal was successfully sent.
-V, --version
Display version information.
-w, --wait
Wait for all killed processes to die. killall checks once per second if any of the killed processes still exist and only returns
if none are left. Note that killall may wait forever if the signal was ignored, had no effect, or if the process stays in zom-
bie state.
-Z, --context
(SELinux Only) Specify security context: kill only processes having security context that match with given expended regular
expression pattern. Must precede other arguments on the command line. Command names are optional.
FILES
/proc location of the proc file system
KNOWN BUGS
Killing by file only works for executables that are kept open during execution, i.e. impure executables can't be killed this way.
Be warned that typing killall name may not have the desired effect on non-Linux systems, especially when done by a privileged user.
killall -w doesn't detect if a process disappears and is replaced by a new process with the same PID between scans.
If processes change their name, killall may not be able to match them correctly.

danke für das nette workaround

# top -n 1 | grep _pflogd | cut -c1-5

# killall _pflogd
killall: Command not found.
# man killall
man: no entry for killall in the manual.

Schau dir mal "killall" an...in deinem Fall müsste killall _pflogd oder killal pflogd funktionieren...je nachdem wie der Prozess heißt.

hallo geeks!
ich möchte gerne ein mini shell script basteln, das einen bestimmten prozess killt.
das ganze unter csh
der kill befehl ist mir bekannt und ich weiss auch wie ich die procid herausfinde.
aber wie soll ich das jetzt zsammschweissen?

die procid bekomme ich über:

top -n 1 | grep _pflogd | cut -c1-5

kill 'top -n 1 | grep _pflogd | cut -c1-5'

geht nicht

plz help!
